Have o look at the link on the 5th post down covers Ceps. The second picture down is a Cep, Brown cap. white sponge pores underside of the cap that do not bruise, bulbous stalk, and if its cut is white no staining. One other thing there is a similar one called the"Bitter Boletus" its not poisonous but it is bitter as fxck and will ruin any thing you put it in, when I cut a Cep I give it a little lick to test. With Boletes a safe rule of thumb is if there is any red on it any where stalk as well or when you cut it goes blue then leave it. But please get a book and do not eat any thing you are n
